I-blast furnace pulverized coal injection system inohlu olubanzi kakhulu lokusebenzisa amandla kagesi, insimbi kanye nezimboni ze-metallurgical.Kuwo wonke uhlelo, ukulungiswa kwamalahle agxotshiwe kuyisixhumanisi esibalulekile, futhi ikhwalithi yamalahle agayiwe akhiwa ukucutshungulwa kwamalahle aluhlaza inquma ukusebenza kahle kwalo lonke uhlelo.Ngenxa yezidingo eziphezulu zamalahle agxotshiwe kanye nomkhiqizo omkhulu, isigayo sokugaya amalahle asikwazi ukuhlangabezana nezidingo zakhona.Ngenxa yalokho, amakhasimende amaningi ngokwengeziwe aphendukela ekugayweni kwamalahle okusha okuqondile.HCMilling(Guilin Hongcheng), njengoba umkhiqizi amalahle umjovo mpo isigayo roller, yethuI-HLM iphuliwe amalahlempo roller millisetshenziswe kabanzi futhi yaqashelwa ku umjovo wamalahle powdermpo roller mill umugqa wokukhiqiza.Okulandelayo yisethulo sezinzuzo zezobuchwepheshe zomshini wokugaya amalahle aqondile acutshungulwa amalahle ahlutshiwe:

Impushana yomjovo wamalahlempo roller mill

Inqubo ephelele yokujova amalahle esithandweni esiqhumayo kufanele ihlanganise indawo yokugcina amalahle eluhlaza kanye nesistimu yokuthutha, isistimu yokuhlikihla, isistimu yokudlulisa amalahle ehlutshiwe, isistimu yomjovo, isistimu yokuphakela igesi kanye nesistimu yokulinganisa amalahle ehlutshiwe.Isikhungo sokulawula ikhompuyutha sohlelo lomjovo wamalahle.Uhlelo lokuhlikihla luyingxenye ebalulekile yenqubo yokujova amalahle esithandweni somlilo oqhumayo, futhi umshini wokugaya oma mpo ucubungula amalahle aputshuziwe kuyinqubo eyinhloko yohlelo lokuphulula.Ukulungiswa kwamalahle agaywe ngomshini wokugaya amalahle kubhekise ekugayweni kwamalahle aluhlaza abe amalahle agayiwe anosayizi wezinhlayiyana kanye nokuqukethwe kwamanzi okuhlangabezana nezidingo zokujova isithando somlilo ngokusebenzisa isigayo samalahle esime mpo ngaphansi kwezimo zomnotho ezivunyelwe.Uhlelo lokuhlikihla luhlanganisa ikakhulukazi ukuphakela, ukomiswa nokugaya, ukuqoqwa kwempushana kanye nokukhipha uthuli.Ekushicileleni amalahle nge-bituminous, ukucindezela okuhambisanayo kokuvikela ukuqhuma kanye namadivayisi ahambisanayo okuqapha nokulawula kufanele futhi asethwe.Inqubo ye-vertical roller mill processing coal pulverized coal: amalahle aluhlaza athunyelwa phakathi kwe-turntable ngepayipi lokudonsa amalahle, futhi amandla aphakathi nendawo akhiqizwa ukujikeleza kwe-turntable enza amalahle ahambe ngokuqhubekayo emaphethelweni e-turntable, futhi ilahle liyachotshozwa lapho lidlula ngaphansi kwama-roller.Indandatho yezindandatho zokuvimbela ifakwe onqenqemeni lwe-turntable, engavimbela amalahle ukuthi angasheleli ngokuqondile ku-turntable.Ngemva kokuba umoya owomile ungeniswe ekamelweni lomoya ovela embotsheni yomoya, ungena engxenyeni engenhla ye-turntable ngokusebenzisa i-annular air duct ezungeze i-turntable ngesivinini esingaphezu kuka-35m / s.Ngenxa yomphumela wokungeniswa kokugeleza komoya, amalahle agayiwe alethwa kusihlukanisi sempushana emahhadla emshinini wamalahle.Kukhona futhi indilinga yama-blades azungeza ne-turntable ezungeze i-turntable.Umsebenzi we-blade ukuphazamisa ukugeleza komoya, ukuze i-powder yamalahle efanelekayo ingene ku-separator ye-powder eqinile engxenyeni engenhla yomshini wokugaya amalahle.

Yiziphi izinzuzo zobuchwepheshe zokugaya i-roller eqondile yokucubungula amalahle aputshuziwe?Ngokwejubane lesigayo samalahle, ingahlukaniswa ibe isigayo sokugaya amalahle esinesivinini esiphansi kanye nesigayo samalahle esinesivinini esimaphakathi.Isigayo samalahle esinesivinini esiphansi sibizwa nangokuthi isigayo se-steel ball noma i-ball mill, kanti ijubane lesilinda ngu-16.～25r/min.Isigayo samalahle esime mpo siyisigayo samalahle esinesivinini esimaphakathi esinesivinini esijikelezayo esingu-50-300 r/min.Iumshini wokugaywa oma mpo ungcono kune-steel ball mill ekucubunguleni amalahle agayiwe, futhi iyisigayo samalahle esisetshenziswa kakhulu ohlelweni olusha lokugaywa kwamalahle njengamanje.Inqubo yokucutshungulwa kwamalahle agayiwe ngomshini we-roller mpo inezinzuzo zesakhiwo esihlangene, indawo encane yaphansi, ukutshalwa kwezimali okuyimali ephansi, umsindo ophansi, ukusetshenziswa kwamanzi okuphansi, ukusetshenziswa kwensimbi okuphansi kanye nokusetshenziswa kwamandla okuphansi kwamalahle okugaya.Ukusetshenziswa kwamandla kwe-vertical roller Mill ukucubungula amalahle aputshuziwe ngokusobala kuyehliswa ngesikhathi sokusebenza komthwalo ophansi, futhi ukusetshenziswa kwamandla ngeyunithi yamalahle agayiwe akukhuphuki kakhulu.Lapho kusetshenziswa isihlukanisi sempushana ejikelezayo esimahhadlahhadla, amalahle agayiwe anokufaniswa okuhle kanye nenkomba ephezulu yokufana.

HCMilling(Guilin Hongcheng), njengomkhiqizi wepulverized amalahleukugayaisigayo, inamakesi acebile amakhasimende kanye nolwazi oluvuthiwe lobuchwepheshe ekucutshungulweni kwesigayo se-roller eqondile yamalahle ahlutshiwe, okunikeza ukusekelwa okuqinile kwemishini kumakhasimende we-vertical roller Mill ecubungula amalahle acijile.Uma unezidingo zokugaya amalahle mpo, sicela csithinteukuze uthole imininingwanefuthi usinikeze imininingwane elandelayo:
